That does seem a bit strange: what are you trying to do? You can't do it just on keystrokes (what if the user moves the caret via the mouse? Or selects a couple of lines then types?
Use the "Improve question" widget to edit your question and try to explain what you are trying to achieve, rather than how t=you are trying to do it.

Another way,

C#

class Program
{
    static string GetLastWord(string dataToTest)
    {
        return String.IsNullOrEmpty(dataToTest) ? default(string) : dataToTest.Split(new char[] { ' ' }).LastOrDefault();
    }

    static void Main(string[] args)
    {

        string dataToTest = "Hello world I am a String!";
        string lastWord = GetLastWord(dataToTest);
    }
}

:)

Solution 1

C#

int prevInd = 0;
string lastWord = "";
private void richTextBox1_TextChanged(object sender, EventArgs e)
{
    if (richTextBox1.Text.Length == 0)
        return;
    if (richTextBox1.Text[richTextBox1.Text.Length - 1] == ' ')
    {
        lastWord = richTextBox1.Text.Substring(prevInd, richTextBox1.Text.Length - prevInd);
        prevInd += lastWord.Length;
        MessageBox.Show(lastWord);
    }
}
